Description

BATTERY ASSEMBLY OF MOBILE TERMINAL

The present invention relates to a mobile terminal, and more particularly to a battery assembly of a mobile terminal having an improved structure to increase the sealing effect of the mobile terminal battery.

In general, a mobile terminal is a terminal that can be used freely while moving regardless of a place. Representative examples thereof include a mobile communication terminal such as a mobile phone and a personal digital assistant (PDA) called a personal portable terminal. Therefore, the term 'mobile terminal' as used herein is a term that includes them all, but for the convenience of description, the following description will be limited to the PDA.

In a complex and diversified society, each individual has a need to store and maintain his or her own information, and various products are currently on the market to meet such individual needs. One of them is PDA (Personal Digital Assistant). PDA, also known as a pocket computer, is a generic term for a palm-sized, small device that has calculation, data storage, and retrieval functions for personal and business purposes, and is often used to maintain schedule calendars and address book information.

In particular, industrial personal digital assistants (PDAs) are currently being used mainly in the logistics industry, and the market is gradually expanding. Industrial PDA is a PDA with a variety of office functions such as barcode scanner and card payment machine which are not found in general PDA. The use of industrial PDA has the advantage of efficient delivery, data management and related tasks. For example, insurers can carry out various insurance-related tasks such as customer information management, customer search, schedule management, counseling logbook management, anniversary search, and invoice processing. In hospitals, medical records, medical history, prescriptions, and image images and graphics such as X-rays can be entered or searched by an industrial PDA carried by medical personnel without time and place restrictions. Of police officers are allowed to pay the traffic law violation penalties that can be paid only 2-3 days after the crackdown. This can dramatically shorten the time.

As can be seen that the industrial PDA is used in the various industrial fields described above, unlike the general PDA, the industrial PDA should have a certain level or more of a requirement that can withstand the industrial environment. In other words, unlike general PDAs, industrial PDAs may be used in freezing warehouses below 10 degrees Celsius and may also be used for a long time outdoors. It must be equipped with impact resistance, water resistance and heat / cooling to be competitive as a product. As such, industrial PDAs must be made more robust and firm than ordinary PDAs, and must be waterproof to resist snow or rain.

On the other hand, such an industrial PDA is provided with a rechargeable battery for supplying power required for the operation of the electronic components embedded in the terminal body, the rechargeable battery is embedded in a battery assembly consisting of a battery case and a battery cover, the battery assembly is a terminal body The battery compartment provided in the rear case of the detachable.

Conventional battery assembly is coupled to the battery case so that the battery cover to cover the upper opening surface of the battery case in the state that the built-in rechargeable battery in the battery case, at this time, the fusion bonding between the battery case and the battery cover do.

However, since the mutual coupling part of the battery case and the battery cover of the industrial PDA is fusion-bonded in the absence of the sealing member, the waterproof and moisture-proof functions of the mutual coupling part of the battery case and the battery cover are weak, so that moisture is prevented from interposing the battery connection area. In addition, foreign matters, etc., may cause serious problems such as battery malfunction and failure.

The present invention has been made to solve the above problems, and an object thereof is to provide a battery assembly of a mobile terminal having an improved structure to increase the sealing effect of a mobile terminal battery such as an industrial PDA.

A perspective view showing a state in which a sealing member is mounted to a case.

As shown in Figures 2 to 5, the battery assembly 100 of the industrial PDA 1 according to a preferred embodiment of the present invention, the battery case 110, the battery cover 130 and the sealing member 150, etc. It may include.

The battery case 110 is manufactured in a rectangular case shape so as to be inserted into a battery slot 11 having a square groove shape provided in the rear case 10a of the terminal body 10, and the battery case 110 may have a built-in rechargeable battery 101. A space 111 is opened (upper surface in Fig. 3). Here, the battery accommodating space 111 of the battery case 110 preferably has an internal space slightly larger than the size of the rechargeable battery 101.

In addition, the battery case 110 is provided with a battery terminal 113 connected to a rechargeable battery terminal (not shown) on one side wall of the inside, and one end of the battery terminal 113 is exposed to the outside of the battery case 110. It is bent and electrically connected to the battery connection terminal 13 provided on the bottom surface of the battery mounting portion 11 of the terminal body 10.

In addition, the battery case 110 is formed with a groove 115 so that the sealing member 150 to be described later is inserted along the edge portion that is fusion-bonded with the battery cover 130 to be described later. Here, the groove 115 has a sufficient depth so that the end of the protrusion 135 of the battery cover 130, which will be described later, in the state where the sealing member 150 is fully inserted, is fitted into the groove 115 to pressurize the sealing member 150. It is desirable to have a width.

The battery cover 130 is fusion-coupled with the battery case 110 to cover the upper opening surface of the battery case 110 in a state where the rechargeable battery 101 is embedded in the battery case 110. Here, the fusion bonding method of the battery case 110 and the battery cover 130 can be understood by a known technique, and thus a detailed description thereof will be omitted.

 In addition, the battery cover 130 is coupled with the upper opening surface of the battery case 110 being slightly inserted into the lower surface of the battery cover 130.

In addition, the battery cover 130 may be detachably attached to the battery mounting portion 11 of the terminal body 10, the battery cover 130 has a coupling protrusion 131 and the coupling groove 133 are formed on both opposite surfaces, respectively. The coupling grooves (not shown) and the coupling protrusions (not shown) formed on opposite sides of the battery mounting unit 11 of the terminal body 10 are respectively fitted.

In addition, when the battery assembly 100 is mounted on the terminal main body 10, the battery mounting part 11 of the terminal main body 10 for a sealing structure such as waterproofing and moisture proof for the mounting area between the terminal main body 10 and the battery assembly 100. The sealing member 140 may be disposed along the outer periphery of the battery cover 130 so that the sealing member 15 may be in contact with the sealing member 15 disposed along the outer periphery.

In addition, the battery cover 130 is pressed into contact with the sealing member 150 inserted into the groove 115 while being inserted into the groove 115 of the battery case 110 along the edge coupling portion fusion-bonded with the battery case 110. Protruding portion 135 is formed.

The sealing member 150 is interposed between the battery case 110 and the battery cover 130 to seal the mutual coupling portion of the battery case 110 and the battery cover 130.
